About the Item

Vivid. Sculptural. Elegantly Bold. This toi at moi ring brings a modern twist to classic elegance. Featuring a 1.57 ct. emerald-cut vivid pink Mahenge Spinel and a 0.62 ct. G-color, VVS1 emerald-cut diamond, the design creates a bold interplay of color and light. Handcrafted in 18K yellow gold, it’s made to stand alone or be effortlessly layered—an everyday statement with a refined edge. Available in size 6.5. Resizing upon request. Why Mahenge Spinel? Coveted by collectors for its vivid, almost neon glow, Mahenge spinel remains one of the most captivating and underappreciated gemstones in the world. Its rarity stems from limited supply, yet its brilliance rivals that of far more famous stones—so much so that some of the world’s most iconic “rubies,” including the Black Prince’s Ruby in the British Crown Jewels, are actually spinels. ABOUT SONYA K. SONYA K. was born from a moment of clarity in a world turned upside down. What began as a childhood love for gems evolved into a calling during the uncertainty of the COVID-19 pandemic and the heartbreak of war in Ukraine. Founded in 2022 by Sonya Konstantinovsky, the brand stands for timeless design, effortless elegance, and versatility. At the heart of each piece is a meticulously chosen gem—tsavorite, spinel, tourmaline, unheated sapphire—selected not only for its beauty, but for its emotional resonance. Paired with bold geometric diamonds and set in clean-lined silhouettes, each design balances masculine structure with feminine fluidity and ease. The SONYA K. design philosophy is rooted in the belief that a gemstone’s beauty should be enhanced, never overwhelmed. Minimal, refined silhouettes allow each stone to speak for itself. “I’ve always admired the glamour of Hollywood’s Golden Age, but much of its jewelry feels too extravagant for modern life. Colored gems were often lost among the sea of diamonds, their natural beauty overshadowed. I wanted to create pieces where the gem takes center stage—bringing Old World glamour into a modern context, while staying relevant for the generations to come.” At SONYA K., we see gemstones and people as remarkably alike—both take time to form, and both carry marks of the paths they’ve taken. We believe your jewelry should reflect your story: unique, evolving, and full of depth. That’s why we work only with rare, exceptional gems, crafting each piece to be lived in, layered with memory, and passed on with love. Like a lifelong companion, our jewels are here to witness your journey—and one day, to accompany the next generation on theirs, carrying a piece of yours with them.
